Owner's manual

NOTE: In cold weather, use of Recirculation mode may
lead to excessive window fogging. The recirculation feature
may be unavailable (soft-key button greyed out) if condi-
tions exist that could create fogging on the inside of the
windshield. On systems with Manual Climate Controls, the
recirculation mode is not allowed in Defrost mode to
improve window clearing operation. Recirculation will be
disabled automatically if this mode is selected. Attempting
to use Recirculation while in this mode will cause the LED
in the control button to blink and then turn off.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. A
solution of 50% ethylene glycol antifreeze coolant and 50%
water is recommended. Refer to “Maintenance Procedures”
in “Maintaining Your Vehicle” for proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper
coolant selection. Use of the air Recirculation mode
during Winter months is not recommended because it
may cause window fogging.
Vacation/Storage
Any time you store your vehicle or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in
fresh air with the blower setting in high. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
